In Episode 21, "The Fox and the Wolf", we learn the origin of the nogitsune from
Kira’s mother, Noshiko Yukimura, who, it turns out, is 900 year old.

She tells the tale of how, back in World War II, she was part of a group of
Japanese-Americans who were imprisoned at the Oak Creek internment camp.

While there, she falls in love with a soldier. But during a riot at the camp, her lover
is burned to death by a female werewolf, while she is shot and presumed dead.
Seeking revenge, Noshiko calls forth the dark spirit of the nogitsune to possess her,
but instead the nogitsune enters the badly-burned body of her dead soldier,
and sets out killing everyone at the camp - until she stops it.

These military flashback scenes were filmed at the old former Army barracks ofFort MacArthurnow part of Angels Gate Park, atop a hill at 3601 S. Gaffey Street,
inSan Pedro,California.

The wooden barracks sit just north of the Korean Friendship Bell, and
now house the Angels Gate Cultural Center and its artist galleries.

Here is a photo of those barracks today:

San Pedro is the southernmost part of Los Angeles,
located at the Port of Los Angeles harbor.

Although internment camps were very real, Fort MacArthur was not one of them.
During the war, the Fort helped protect the harbor from the threat of invasion from sea.

It was an active Army post from 1914 to 1974. Now part of a park, visitors can see
the former big gun emplacements, bunkers, tunnels, etc. There is also a smallFort MacArthur Museum nearby, telling the history of the former Fort.

In fact, in Episode 23, when the team returns to the now-deserted Oak Creek to rescue
Lydia, those night time battle scenes were filmed at the Fort MacArthur Military Museum,
near one of the Army trucks they have on display there, and down in the concrete bunker
known as Battery Osgood-Farley, which lies just south of the Cultural Center/barracks:
